Up until now, the primary strengths of The Diplomat have been the exceptional actors and the clever dialogue that allows them to shine. Both of those assets remain firmly in place for season three, but what impresses me most now is how the series manages to revolve around American politics while still delivering characters worth getting invested in.
The show — which involves American Ambassador to the United Kingdom Kate Wyler (Keri Russell), her scheming husband Hal (Rufus Sewell), and a swirl of high-stakes intrigue centered around a scandalous false-flag operation in the Middle East — started out a conventional fictionalization of political drama. But now, after a year of Trump’s disastrous return to power, it increasingly feels like a show set in a straight-up alternate universe — one where the truth still matters, the established world order isn’t collapsing, and politicians in power still have nuanced approaches and semi-good intentions. In 2026, all of that reads like high fantasy, but The Diplomat has such a capable, committed cast that one can shrug away disbelief for the duration of each lightning-fast episode and simply enjoy the ride.
Consider the major plot points of season three (spoilers ahead): The sudden death of the U.S. president at the end of season two elevates Grace Penn (Allison Janney) to the presidency. This is a problem because, well, Penn was the mastermind behind a false-flag operation that killed over forty British sailors — a politically motivated shitshow manufactured in the interests of blowhard UK Prime Minister Nicol Trowbridge (Rory Kinnear). Why did the president die? Because Hal shocked him by telling him about the plot. And who is the most likely candidate to step in as the secretly traitorous Penn’s new VP? None other than Kate Wyler. On the page, this extraordinary scenario reads as laughably contrived. But it’s just the tip of an intricate iceberg, one that maneuvers the players through a chaotic muddle of crises, ever-hurtling toward disaster. Indeed, in the wrong hands, The Diplomat would come off as a campy, implausible soap opera, a vibe which does in fact threaten to emerge during the odd “idiot plot” moment.
Somehow, though, it never falls apart, and in fact it sings along above the unlikely, pretzelesque twists of the conspiracy by focusing on the people and their conflict-laden interactions. The political backdrop is both a MacGuffin, faciliating the drama, and a metaphor, highlighting the broken systems that propel our “heroes” through their scheming paces, which never entirely vindicate them (or, for that matter, our rubbernecking investment in their fates). For all the fervorous disagreement — anchored by a truly remarkable onscreen dynamic between Russell and Sewell — it’s somehow possible to overlook that the controversies of The Diplomat look benign compared to the actual nightmare geopolitics of 2026.
It’s a testament, then, to the writing and the performers — including Ali Ahn, Ato Essandoh, David Gyasi, Nana Mensah, and (in an inspired piece of casting) Bradley Whitford — that one can reach the end of each episode of The Diplomat both dazzled by and invested in situations that, contemplated in the cold light of a cataclysmically dysfunctional reality, should leave us rooting for nobody. It’s quite a feat, and for as long as it can be sustained, I’ll surely keeping watching.
